Also called shaken baby syndrome, this is a type of non-accidental head-injury to infants, which results in cerebral haemorrhage and can cause severe brain damage or even death. There is controversy as to whether it can be caused simply by violent shaking or whether impact against a hard surface is also necessary. In addition, some pathologists claim that identical lesions can be seen when the brain is examined microscopically after a fatal choking attack or other reason for oxygen starvation.
